Answer]: a, b, d

This question examines the masonry body. According to the provisions of "Sintered Ordinary Bricks" (GB T 5101-1998), bricks with qualified strength and weathering resistance are divided into three quality grades: excellent product (A), imitation dust spike (B) and qualified product (C) according to the size deviation, appearance quality, frost and lime bursting index.

Summary. For every 150,000 batches less than 150,000 pieces, 10 bricks were sampled for each group of bricks with a strength grade. "Sintered Ordinary Bricks" stipulates that all bricks with clay, shale, gangue and fly ash as the main raw materials, and are formed and roasted into solid or porosity of no more than 15% are called sintered ordinary bricks.

The provisions of pre-sintered ordinary bricks GB+5101-2017 stipulate how much should be extracted when each batch of sintered ordinary bricks is inspected for strength grade.

For every 150,000 batches less than 150,000 pieces, 10 bricks were sampled for each group of bricks with a strength grade. "Sintered Ordinary Bricks" stipulates that all cavity belts with clay, shale, coal gangue and fly ash as the main raw materials of Wulinglu, and the solid Wangyan or bricks with a porosity of not more than 15% are formed and roasted, which are called sintered ordinary bricks.

1. For the same origin and the same specification, every 150,000 pieces is a test batch, and less than 150,000 pieces are also counted as a batch; 2. Take a group (10 pieces) of sintered bricks for each acceptance batch to do the strength grade test; 3. Take a group (10 pieces) of steaming bricks for each acceptance batch for strength grade test. Sampling method: 1. Randomly selected in the finished product stack according to the sampling scheme; 2. The appearance quality of the cherry blossom hole of the specimen must meet the external rot and virtual index of the finished product; 3. If there is any doubt about the test results, the specimen can be doubled for retest.
